Phalloidin staining. In addition, rhodamine phalloidin can be used for staining the actin cytoskeleton in cells, and also as a fluorescent marker/stabilizer for microfilaments used in motility assays The rhodamine phalloidin is provided as a lyophilized powder When reconstituted with 500 µl methanol, it is at 14 µM (0 x stock) Purity. For certain phalloidin conjugates, especially CF®405M, CF®555, CF®647, and CF®680, we recommend imaging immediately or shortly after staining Staining with our other CF® dye phalloidins usually is stable for up to a week when specimens are stored at 4°C, protected from light. We usually do our rhodmainephalloidin staining over night at 4ºC (rotating/shaking), together with the secondary antibodies in PBS containing 03% TritonX The perfect protocol depends probably.

Phalloidin and Phalloidin Conjugates for Staining Actin Filaments Introduction Actin is a globular, roughly 42kDa protein found in almost all eukaryotic cells It is also one of the most highly conserved proteins, differing by no more than % in species as diverse as algae and humans Actin is the monomeric subunit of two types of.
